Chemical Structure
Description
N-(1-Methyl-2-oxo-1,2,3,4-tetrahydroquinolin-6-yl)-2-(thiophen-2-yl)acetamide (C16H16N2O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
N-(1-Methyl-2-oxo-1,2,3,4-tetrahydroquinolin-6-yl)-2-(thiophen-2-yl)acetamide (CAS 921999-33-9) is a high-purity analytical reference standard with the molecular formula C16H16N2O2S and a molecular weight of 300.38 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
